Numerical Investigation of Newtonian Flow Characteristics in Canal with Gradual Expansion

The goal of a present study is to investigate the vortex characteristicsproduced in neighbor wall of canal with gradual expansion in 2D state and expansion ratio is 1:3. In present research theNewtonian fluid flow through canal assume laminar and it is investigated four angles 30, 45, 60 and 90 degree. Discretization of governing equations is performed using finite volume method and for couple of velocity and pressure parameters used the PISO algorithm on a staggered mesh. In all old researches vortexes length investigated for sudden expansion. The main innovation of current study is Investigated and reported regular and classified resultsfor every vortex length, maximum height and length of maximum height, start point and end point for length of vortexes in angles of 30, 45 and 60 degree in the range of Reynolds number in tables .the streamline and contour of velocity for flow through canal is investigated and plotted for various Reynolds number.
